Abstract
Baits useful against insects contain a homogeneous mixture of: (a) a binding agent comprising a polymer that is solid at 25.degree. C. and exhibits a melting point within the range from about 35.degree. C. to about 65.degree. C.; (b) an erosion rate modifier for said binder; and (c) 0.01-99 wt % of an insecticide; and (d) 0.01-99 wt % of a feeding stimulant for the target insect population.
Claims21
A particulate bait composition useful for controlling insect populations, said composition comprising a homogeneous mixture of:
- (a) a binding agent comprising a polymer that is solid at 25.degree. C. and exhibits a melting point within the range from about 35.degree. C. to about 65.degree. C. and is selected from the group consisting of polyethylene glycol, block copolymers of ethylene oxide and propylene oxide, solid fats, monoglycerides, diglycerides;
- (b) an erosion rate modifier for said binder;
- and
- (c) 0.01-99 wt % based on total weight of said bait of an insecticide;
- and
- (d) 0.01-99 wt % based on total weight of said bait of a feeding stimulant for said insect population selected from the group consisting of a cucurbitacin and corn germ having less than 10% endosperm associated therewith and in the form of a finely divided particulate or liquid.
A method for controlling insect populations on plants consumed by said insects, said process comprising:
- applying to an area exhibiting infestation by an insect that feeds on cucurbitacin-containing plant tissues an amount of a particulate bait effective to kill at least a portion of the immature or adult insects in said, wherein said bait comprises a homogeneous mixture of:
- (a) a binding agent that is solid at 25.degree. C. and exhibits a melting point within the range from about 35.degree. C. to about 65.degree. C. and is selected from the group consisting of polyethylene glycol, block copolymers of ethylene oxide and propylene oxide, solid fats, monoglycerides, diglycerides, and triglycerides;
- (b) an erosion rate modifier for said binder that reduces the solubility of said binding agent to less than about 5% by weight in water at 25.degree. C.;
- (c) 0.01-99 wt % of an insecticide;
- and
- (d) 0.01-99 wt % of a feeding stimulant selected from the group consisting of a cucurbitacin and corn germ having less than 10% endosperm associated therewith.
